1. An apparatus for measuring the length of filamentous textile material wound onto a lap beam as a yarn sheet, and in particular, onto a dyeing beam, said apparatus having a pressure means that applies pressure to the beam lap during the winding process, which pressure means is mechanically connected with a displacement transducer that emits measurement impulses, said apparatus including a beam-driven shaft encoder that emits a predetermined number of calculation impulses for each revolution of the beam, and with a computer that calculates the partial lengths of laps on the lap beam from the measurement impulses and the calculation impulses, adding them, characterized by the fact that the displacement transducer connected to the pressure means that applies pressure to the beam lap is operatively connected by means of a sliding articulation with a distance staff, which is also hinged so as to have an extension of its longitudinal axis intersect the longitudinal axis of the lap beam, and wherein the computer provides a correction factor that renders it possible to consider the diameter of the axle of the lap beam and the position of the point of articulation of the distance staff with the pressure means that applies pressure with regard to a pressure point in line with the distance staff to accurately calculate the length of textile material wound on the lap beam.
